  • Patent number: 11973129
    Abstract: A method for forming a semiconductor device structure is provided. The semiconductor device includes forming nanowire structures stacked over a substrate and spaced apart from one another, and forming a dielectric material surrounding the nanowire structures. The dielectric material has a first nitrogen concentration. The method also includes treating the dielectric material to form a treated portion. The treated portion of the dielectric material has a second nitrogen concentration that is greater than the first nitrogen concentration. The method also includes removing the treating portion of the dielectric material, thereby remaining an untreated portion of the dielectric material as inner spacer layers; and forming the gate stack surrounding nanowire structures and between the inner spacer layers.

  • Patent number: 11967596
    Abstract: An integrated circuit includes a first-voltage power rail and a second-voltage power rail in a first connection layer, and includes a first-voltage underlayer power rail and a second-voltage underlayer power rail below the first connection layer. Each of the first-voltage and second-voltage power rails extends in a second direction that is perpendicular to a first direction. Each of the first-voltage and second-voltage underlayer power rails extends in the first direction. The integrated circuit includes a first via-connector connecting the first-voltage power rail with the first-voltage underlayer power rail, and a second via-connector connecting the second-voltage power rail with the second-voltage underlayer power rail.

  • Publication number: 20240113112
    Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.

  • Publication number: 20230185581
    Abstract: A method is provided of swapping code execution among multiple microcontroller code banks. The microcontroller has computer-readable memory, a central processing unit, and an interrupt controller. The method comprises executing an instruction to process a first pointer storing an address location of a first application within a first code bank of computer-readable memory. The first application is executed based on processing the first pointer. The method also comprises replacing the address location of the first application stored within the first pointer with an address location of a second application stored with a second code bank of the computer-readable memory. The instruction to process the first pointer is executed to process the address location of the second application to execute the second application without stopping operation of the interrupt controller.
